Abstract：

[Objectives]  The objective of this study is to assess the effects of the transgenic Bt rice “Ganlv1”on the arthropod communities in paddy fields. [Method]  The rice expressing a fusion gene derived from cry1Ab and cry1Ac and a conventional control rice were investigated inNanchang County,JiangxiProvince in 2012 and 2013. [Result]  No significant differences in community indices such as species richness, dominance index, Shannon-Wiener diversity index and evenness index in the transgenic Bt rice plots compared with the control rice plots . Moreover, there were no significant differences in the five guilds dominance in the transgenic Bt rice plots and the control rice plots. Mosts of the dissimilarities between the arthropod communities in the transgenic Bt rice plots and the control were apparently low. [Conclusion]  It was apparent that the transgenic Bt rice “Ganlv1”had no significant adverse impact on the arthropod community structure under the field conditions.
